Mathematics
1 answer:
WITCHER [35]3 years ago
6 0

Answer:

A. 11

Step-by-step explanation:

BC×AC = DC × LC

7(2x +3 +7 ) = 9 ( x+ 1 +9)

7 ( 2x +10) = 9( x + 10 )

14x - 9x = 90 - 70

5x = 20

x = 4

then,

AB = 2x + 3

= 2× 4 + 3

= 11

Find an equation for the line that passes through the points (-6, -6) and (4,-2)
Viefleur [7K]

Answer:

y = 2/5 x - 18/5

Step-by-step explanation:

y = mx + b

m = (y2 - y1)/(x2 - x1) = [-2 - (-6)]/[4 - (-6)] = 4/10 = 2/5

y = 2/5 x + b

-6 = (2/5)(-6) + b

-30 = -12 + 5b

5b = -18

b = -18/5

y = 2/5 x - 18/5
